Dell PowerStore Configuring Volumes

Create a volume

1. Under Storage, select Volumes.
2. Click Create.
   NOTE:You can also create volumes when you create a volume group.
3. In the Create Volumes slide-out panel, enter the following volume information:
   • Name (or Prefix): When you create a single volume, this name is the name of the volume. When you create multiple volumes, this name is the base name to which a number is appended.
   • Category: Select a category from the drop-down menu for the type of application that you want to associate with the volume. You can select Business Applications, Relational Databases, and so on.
     NOTE:Selecting a Category for the application is required in PowerStore Manager 2.1. This field cannot be left blank.

     You can select Other if the categories in the drop-down menu do not match the type of application that you are using. After you select Other, type the application name in the Application field.

   • Application: Select the application from the drop-down menu.
     NOTE:Selecting an application is required in PowerStore Manager 2.1. This field cannot be left blank.

     If you do not see the application that you want in the drop-down menu, you can type it into the Application field. You can manually enter the name of an application whether you choose one of the selections under Category or select Other, from the drop-down menu. The maximum number of characters is 32.

   • Quantity: You can add up to 100 volumes that have the same properties. The system appends the volume name with a number when creating multiple volumes.
   • Size: The size is the quantity of storage that is subscribed for the volume. After you create the volume, you can increase its size but not decrease it. PowerStore supports the creation of thin volumes up to 256 TB in size.
   • Placement: You can place the volume in an appliance that is shown in the drop-down list, or allow the system to place the volume automatically.
   • Associated Volume Group (optional) : Select which volume group that you want to associate the volume with.
   • Volume Protection Policy (optional): Select a protection policy that contains snapshot and replication rules applicable for the volume. You can add a protection policy after creating the volume.
   • QoS Policy (optional): Select a QoS policy to set maximum limits on IOPS or bandwidth, or both, on the volume.
   • Volume Performance Policy: Set the performance profile on volumes to service IOPS when there is contention for resources at the system level. Limit I/O throughput and bandwidth to provide more predictable performance.

     Select a Performance Policy consistent with the I/O priority (High, Medium, or Low).

   • Available Hosts/Host Groups (optional): Select the storage protocol and then select the hosts or host groups that can access the volume. The radio buttons to select the protocol only appear if the storage protocol has not been set.
     NOTE:A volume can be attached to either a SCSI or NVMe host. Volume migration and replication use iSCSI for transport.

     When you connect the volume to the hosts or host groups, you can specify a Logical Unit Number. The Logical Unit Number panel appears only if you select SCSI for the host. If a Logical Unit Number is not specified, the system assigns one by default. You can add hosts or host groups after creating the volume.
